Hello, I can note send messages from my webmail (Horde/IMP) to myself or any user in my domaine. No problem to sent messages for other domaines, that works fine . In the following the output of the sendmail (Qmail wrappers) maillog on the Relay machine (where Horde/IMP, Qmail, apache are installed) and that of my LAN mail server (Courrier-IMPA, users's account, Qmail). Just trying to sent messages to myself is loggged as: Relay machine maillog file: ------------------- Jan 11 09:19:34 phoenix sendmail[1960]: JAA01960: Authentication-Warning: phoenix.linuxatbusiness.com.linux-lab.com: httpd set sender to [EMAIL PROTECTED] using -f Jan 11 09:19:34 phoenix sendmail[1960]: JAA01960: [EMAIL PROTECTED], delay=00:00:00, mailer=local, stat=User unknown Jan 11 09:19:34 phoenix sendmail[1960]: JAA01960: [EMAIL PROTECTED], size=321, class=0, pri=30321, nrcpts=1, msgid=<[EMAIL PROTECTED]>, relay=httpd@localhost Jan 11 09:19:34 phoenix sendmail[1960]: JAA01960: [EMAIL PROTECTED], delay=00:00:00, mailer=local, stat=User unknown Jan 11 09:19:34 phoenix sendmail[1960]: JAA01960: JAB01960: postmaster notify: User unknown Jan 11 09:19:34 phoenix sendmail[1960]: JAB01960: to=admin, delay=00:00:00, xdelay=00:00:00, mailer=local, stat=Sent Lan machine maillog file: ------------------ Jan 11 09:37:20 andromede imaplogin: Connection, ip=[::ffff:10.1.7.200] Jan 11 09:37:20 andromede imaplogin: LOGIN, user=ouldm, ip=[::ffff:10.1.7.200] Jan 11 09:37:20 andromede imaplogin: LOGOUT, user=ouldm, ip=[::ffff:10.1.7.20 NOTE: Relay and Lan servers are separated by firewall which allows POP, IMAP trafic betwen the two machines, 10.1.7.200 is the firewall ip.
